This applies to the Memory function only.
A magnified section of a waveform can be displayed together with the unmagnified view by splitting
the screen horizontally.
With the waveform displayed normally on the upper half of the screen, a section magnified along the
time axis can be displayed on the lower half.

When you press the PRINT key while using the Zoom function, the waveform
displayed on the lower half of the screen is printed. (The print format will be as
for a single screen waveform. If the A/B cursors are used, the selected section
will be printed.)
Procedure
To open the screen: Press the DISP key
→
Waveform screen
1
Move the cursor to the magnification.
2
Select [Zoom On] .
The Zoom function is enabled and the screen is split into upper and lower
halves.
(Upper: waveform to be magnified, Lower: magnified (zoomed) section of
waveform)
3
Select display magnification for the zoomed waveform sec-
tion.
Move the cursor to the [Zoom Mag] , and set the magnifica-
tion.
The zoomed waveform section at the lower half of the screen is magnified.
When the same value or a smaller value than the magnification/compression
ratio is specified, the ratio is automatically set to a setting one step higher
than the
[Zoom Mag] setting.
4
Scrolls the zoomed section of the waveform.

To cancel Zoom:
Move the cursor to the magnification, and select
[Zoom Off] .
(The condition is canceled while keeping the inherited zoom
ratio.)
Example: When the zoom ratio was set to x5 and zoom is
canceled, the ratio setting will be [x5] .
